This Cinemork Woodridge is the newest of the three theaters in this case study. At the time of this printing, only the block walls have been erected. Tony Chapman of TK Architects and Walloce Engineering incorporated the highest order of slender wall technology which demonstrate the efficiency of a well designed and engineered masonry wall system.
In figure 1 to the left, we ses a typical wall section using a 12 inch grouted and reinforced concrete masonry unit. Wolls ore designed as a simple spon from floor to roof deck with no intermediate supports. Figure 2 shows the reinforcing scheme graphically, while figure 3 shows the schedule of bor sizes and spocings.
As we described in the first project, Melrose Pork, by placing two reinforcing bars in one core, maximum efficiency is achieved. Figure 4 on the right shows a plan view of the doubly reinforced unit. Spacers are used to ensure that the proper embedment and moment arm distance are consistently achieved.
Masonry's competitors stote that a structure like this takes for too long to complete. Mulligan Masonry was able to prove them wrong by erecting all of the immensely toll slender walls in just 14 weeks.
Although the section on the left shows a brick veneer on the exterior, this is only used in strategic locations. The main exterior finish for this project is a combination of painted smooth face and split foce block, with brick veneer used as a visual accent. TK Architects and Wallace Engineering showed us the versatility of masonry as both structure and finish with these three projects.
Decorative pilasters are used to break up the giant facades. These pilosters are corefully detailed combino tions of brick and concrete masonry. The drowings to the right show how these pilosters are created.
With toll slender wall systems such as these, temporary woll bracing during construction is a pertinent issue. This project demonstrates the stote of the art in bracing today. See the brocing note to the right for more infor motion.
"The project proceeded quickly and efficiently mainly due to the skill and experience of Mulligan's job foreman Dave Sobo. A very aggressive schedule was enacted for this project. The use of Morgan Scaffolding through out and the organization and efficien cy of Mulligan's crews made this job proceed smoothly" - Charlie Richardson, Capitol Construction Group
